Dark Vortex is Yggdrasil's eerie new slot and will be game provider's first slot to offer a Buy Bonus feature. It will launch just in time for operators’ Halloween campaigns.

In the game, players aim to open a portal to the netherworld. When the titular Vortex is fully open, the stacked wilds and 3125 ways to win running from both left and right mean that players could win more than 7000 times their bet size with any spin. Players can open the Vortex either reel-by-reel in base-play or buy straight into the feature.
In base play players can open an ancient vortex with taller reels, more high pays and stacked wilds by hitting two bonus symbols on adjacent reels. Every additional adjacent bonus symbol will grow the portal and give additional Vortex spins.
Expanding the Vortex to cover all reels starts Free Spins with wild stacks up to 10 symbols tall. The new feature introduced with this game also offers a third way into Free Spins – by sacrificing the 80x bet players can activate the Buy Bonus feature and immediately enter the Free Spins round. This option is designed for players who prefer fast-paced, higher stakes play instead of grinding out wins slowly within the base game.
Yggdrasil head of slots Jonas Strandman said: “Our humorous take on the Lovecraftian universe is no joke – the more than 7000 times max bet win is the third highest for any Yggdrasil game. Add to this the excitement of the innovative Vortex reels and the chance to buy straight into the Free Spins, and we've got a game that we know will be highly appreciated by seasoned slots spinners, while at the same time being a great gateway to the reels for new players.
“Operators already seem to share this sentiment as many of our clients have chosen to run their Halloween campaigns on our seasonably suitable dark little gem. Put all that together and we have the makings of an occult classic.”
